The Knowledge Consistency Checker (KCC) is an active directory process that runs on domain controllers and automatically identifies or calculates the most efficient replication topology for the network using data provided by the network in active directory sites and services. To improve replication traffic in most networks, the ISTG might be enabled so that KCC can logically generate (Create) connection objects based on the physical network layer. This is good because KCC will only create connection objects in active directory if it is required for a particular site.
ISTG Reference numbers:
0:To  Enable ISTG
1:To disable automatic intrasite topology generation
16:To disable automatic intersite topology generation
17:To disable both intrasite and inter-site topology generation Read more…

I thought I should post my response in my blog, just in case same question might came up again.

Active Directory Replication:Each Windows Server Domain controller holds a copy of the Active Directory database and each domain controller must be updated when a change occurs. This process of sending updates between domain controllers is called replication. Replication ensures that Active directory is always up to date and current across the entire network Active Directory environment. Read more…
